It is possible to set up transactions/BAPIs,
screens or fields in order to process them only if a given condition exists.
For this, proceed as follows:

Transactions/BAPIs:
If you want to execute a transaction only if a given condition is accomplished,
then next to the transaction code enter the name of a condition separated by
a semicolon. For example:

TRANS

MM01;C1

SAPLKMA1

0300

BDC_OKCODE

'/00'

SGTXT

NORMAL1

BAPI

BAPI_ABSENCE_CREATE;C1

EMPLOYEENUMBER

EMPLOYEENUMBER

VALIDITYBEGIN

VALIDITYBEGIN

VALIDITYEND

VALIDITYEND

ABSENCETYPE

ABSENCETYPE

Screens:
If you want to execute a screen if a given condition is accomplished, then next
to the screen code enter the name of a condition separated by a semicolon. For
example:

TRANS

MM01

SAPLKMA1

0300;C2

BDC_OKCODE

'/00'

SGTXT

NORMAL1

Fields or
OKCODE's: If you want
to fill a field or send an OKCODE only if a given condition is accomplished,
then next to the field or OKCODE enter the name of a condition separated by
semicolon. For example:

TRANS

MM01

SAPLKMA1

0300

BDC_OKCODE;C3

'/00'

SGTXT;C4

NORMAL1

BAPI

BAPI_ABSENCE_CREATE

EMPLOYEENUMBER;C5

EMPLOYEENUMBER

VALIDITYBEGIN

VALIDITYBEGIN

VALIDITYEND

VALIDITYEND

ABSENCETYPE

ABSENCETYPE

Now define the execution
conditions by clicking on the button "Define execution conditions".

Define execution conditions: First
add the name of the condition to be defined. Then select the condition from
the list and write for that condition the necessary ABAP/4 code to determine
if the condition is accomplished (and the transaction, screen or field is to
be sent). To refer to an input file/table field (single file or main table)
use #field.

If the ABAP/4 code determines that
the condition is accomplished, then you must assign YES to the RESULT variable,
otherwise the RESULT variable would be NO and it will not be processed. Examples:

Assume the existence of a condition
C1, the ABAP/4 code could be the following:

IF #TYPE_MATERIAL = 'RAWMAT'.

RESULT = YES.

ENDIF.

Assume the existence of a condition
C2, you wish to process a screen only if material from source file is the
old material, the ABAP/4 associated could be the following:

SELECT SINGLE BISMT INTO #MATERIAL
FROM MARA WHERE BISMT = #MATERIAL.

IF SY-SUBRC = 0.

RESULT = YES.

ENDIF.

The ABAP/4 code manually entered
is not checked and it is the user's responsibility.
